NATURAL INCREASES Meaning and
Definition
-
Natural increases, in the context of demography and population studies, refer to the growth of a population due to the surplus of births over deaths within a particular geographic region or community. It is a measure of population growth that is determined solely by the natural processes of birth and mortality without considering factors such as migration.
When the number of births exceeds the number of deaths, a population experiences natural increase. This occurs when a population has a high birth rate relative to its death rate. The factors that contribute to natural increases include higher fertility rates, improvements in healthcare and hygiene, as well as socioeconomic factors that may affect birth rates, such as cultural or religious practices.
Natural increases can be measured and expressed as a specific rate, commonly referred to as the natural increase rate (NIR). The NIR is usually calculated by dividing the number of live births in a specific period by the population size and multiplying the result by a factor (usually 1000). This rate provides an indicator of the pace of population growth resulting solely from births and deaths and is often used by demographers to study population dynamics and make projections.
It is important to note that natural increases do not take into account changes in population size due to migration, which can also significantly impact population growth.

Etymology of NATURAL INCREASES
The etymology of the term "Natural Increases" is actually an interpretation of the two words "Natural" and "Increases".
1. Natural: The word "natural" comes from the Latin word "naturālis" which means "of nature" or "related to nature". It refers to things that exist or occur in the world as a result of natural processes, without any human intervention.
2. Increases: The word "increases" is derived from the Latin word "increasare" which means "to grow, augment, or make greater". It signifies the act or process of becoming greater in size, quantity, or degree.
Combining these two words, "Natural Increases" refers to the growth or augmentation that occurs naturally without any external factors or human intervention. In demographic terms, it often refers to the increase in population due to births and deaths without considering migration.
